SPECIFICATION forming part of Letters Patent No. 488,216, dated December 20, 1892. Application filed January 8|1890- Serial No. 336,238. [No model.) Patented in England September 17,1889, No. 14,

To all whom it may concern.-

Be it known that I, RODOLPHE NroKLtzs, of Petit Quevilly, France, a citizen of the French Republic, have invented certain new and useful Improvements in Apparatus forDyeing, 850., Rovings, Yarn, &c., (for which I have obtained Letters Patent in Great Britain, No. 14,610, dated September 17, 1889,) of which the following is a specification.

This invention relates to the method of and apparatus for mordanting, dyeing, scouring, rinsing and similarly treating cotton and other vegetable fibers in slivers, rovings, yarn or other state of preparation.

My invention consists of the construction and arrangement of an apparatus for dyeing or treating wools, silks, cottons, 850., all of which will be fully described hereinafter.

In the accompanying drawings, which illustrate in what manner this invention may be carried into practical effect;-Figure 1, is an elevation partly in section of an arrangement in which the materials are operated upon in a single vessel or vat; and, Fig. 2, is an elevation partly in. section of an arrangement in which several vessels or vats are employed.

In each of the figures similar letters are employed to denote similar parts.

The air pump and reservoir which are indicated in Fig. 1, are omitted in Fig. 3, but it will be understood, as hereinbefore described, that these or equivalent devices are also employed in conjunction with the multiple arrangement.

Within the Vat or vessel A, in which the slivers, rovings or yarn, hereinafter called the material, is to be treated, there is placed a removable hollow plate B, the interior of which is capable of being placed in communication with a closed receiver 0. The hollow plate B, carries a number of vertical perforated tubes D, opening into the interior of the plate B, and so arranged and constructed that the material E, which is to be treated may be placed around the perforations of the tubes. The closed receiver 0, may be mounted on a permanent support F, Fig. 1, when only one vat or vessel is used, or upon rails F, Fig. 2, when a number of vats are employed in series. In the latter case the closed receiver 0, may be easily moved into a position above or otherwise convenient to any vat in the series. The

entering the lower part of the receiver and communicating with the open vat A by a flexible pipe H; I, also entering the lower part of the receiver and communicating with the hollow plate B; and J, entering the upper part of the'receiver and communicating with a closed reservoir K, which communicates through the pipe M, with an air pump L. In the arrangement shown in Fig. 2,the horizontal pipe J has branch connect ons J occupying positions above the vats so that the closed receiver may thereby be connected to the reservoir K, in any of the positions whlch it may occupy. It will be understood that the pipe J, Fig, 2, communicates wit-h a reservoir similar to the reservoir K, Fig. 1, and that this reservoir also communicates with an air pump or its equivalent as hereinbefore described.

The operation is conducted in the following manner :--The material to be dyed or otherwise treated having been placed around the perforated tubes D, the desired liquid having been placed in the vat A, and the connectlons having been made; valve J, connecting the receiver with the reservoir and valve H, wh1ch controls the passage between the receiver 0, and the interior of the vat A, are opened, and the air cock G, and a valve controlling the passage I, between the receiver 0, and hollow plate B, being closed, the air pump L, 1s put in motion, and the liquid in the vat A is forced into chamber 0 through pipe H. As a consequence the liquid that remains in the pierforated tubes D and hollow plate B is drawn through the material into the vat and from thence to chamber 0. In the second part of the operation the communication H, between vat A, and the receiver, and the communication J, between the receiver C, and the reservoir K, is closed; the air cock G, and valve I, now being open, the liquid will redescend 1n the pipe I, into the hollow plate B, and thence pass outward through the perforated tubes D, and the material around them.

The two operations may be successively performed as often as may be desired.

During the descent of the liquid, its pressure tends to move the material, and to prevent this, aperforated plate P may be placed above it.

A gage glass Q, may be attached to the closed receiver 0, so as to indicate when the liquid has attained a desired height therein at the end of the first partof the operation and when therefore the air valve may be opened.

It is easy to regulate the pressure to suit the material to be treated, by placing the receiver at a greater or less elevation, or simply by regulating the fiowof theli'quid by means of the valve.

The hollow plates with the material thereon may be lifted from and lowered into the vats by means of the lifting tackle R, which, when a seriesofvats are used, may be suspended from'the small traveling crane S.

The reservoir K,is placed between the pump and the receiver 0-, and the liquid placed within said "reservoir is removed therefrom to the receiver'in the following manner. The air pump K, is started and the valve forming the outlet between the said reservoir and receiver being'opened allows the liquid to pass into. the latter under pressure produced by the air pump. The reservoir may be filled 'by a siphon and thenclosed. This operation may. be performed by removing the end of the pipe M. The level of the liquid within the reservoir should not reach quite to the top thereof. The liquid is prevented from entering the pipe M, when the pump is in operation by means-0f valves commonly known and used in connection with pumps. It will, therefore, be obvious that the reservoir K, serves as a storage tank for the supplying of one or a series of vats.

Having now particularly described and ascertained the nature of my said invention and in what manner the sameis to be performed,

I declare that what I claim is.
